IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. lll ,831, datedFebruary 14, 1871.

To all whom it may concern:

Beit known that LNIoHoLAs SEIBERT, of San Francisco, in the county ofSan Francisco and State of California, have invented a new and usefulImprovement in Lubricators; and I do hereby declare that the followingis a full, clear, and exact description thereof,which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

This invention relates to an improvement in A lubricators forsteam-engine cylinders; and it consists in the arrangement of parts, ashereinafter described, and as particularly specified in the claims.

In the accompanying drawings, Figure 1 represents a side view of thelubricator as connected with a cylinder of a steam-engine. Fig. 2 is acentral section of the lubricator detached.

Similar letters of reference indicate corresponding parts.

A is the cylinder.

B is the steam-pipe.

C is the steam-chest.

A is the condensing-pipe connecting the steam-pipe B and lubricator.

D is a reservoir, which is supplied with water by reason of the steamcondensing in the condensing=pipe A.

E is the oil-pipe leading to the cylinder and valve-chest.

F is the cup or reservoir, which contains the oil or otherlubricatinganaterial,

G is a stop-cock or valve in the oil-pipe E.

H is a check-valve.

I represents a waste-cock at the bottom of the oil-reservoir.

J is a glass tube.

K is a sliding gage, which indicates the amount of oil used.

L is the regulating feed valve, which is opened slightly.

The water in the reservoir D being higher and heavier than the oil inthe cup F, forces itself under the oil in the cup F and glass tube J,and passes out through the checkvalve I-I and oil-pipe E into thesteam-pipe B to lubrcate the valves and cylinders.

M is a cock to regulate the admission of steam from the steam-chest intothe oil-cup F when tallow is used.

The cock I is used to draw the Water off when the cup F is to bereplenished.

N is a screw-plug in the top of the oil-cup or reservoir F, throughwhich the oil or other lubricating material is introduced.

O is a vertical tube within the oil-cup F.

P is another vertical tube within O, and q is an annular space betweenthe two tubes.

The tube P is in communication with the steam in the steam-chest bymeans of the passages S S', so that the space q is kept hot by thesteam, which enters it as indicated by the arrow.

R R are passages leading from the oil-reservoir Fto the glass tube J.The oil in the glass tube will stand at the same height as in thereservoir, so that the quantity contained therein may be always visibleto the eye.

The gage K may be set at any time when the machinery is to be putinmotion to indicate the height atwhich the oil stands. Vhen the movementof the machinery has ceased, the distance between the height of the oiland the gage will indicate the precise quantity consumed, (the cubicalcapacity of the reservoir F being known.)

Whatever amount of steam may condense in the tubes O and P will flowback into the steam-chest C by gravity.

The steam-pressure in tubes D and E is at all times equal. I-Ience thegravity of the water in the former will determine the direction of theiiow of oil.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The arrangement of the cock M, passages S S', andtubes C and P, with the oil-reservoir F, and gage .I R, as herein shownandl described, for the purpose speciiied.

2. The improved lubricator consisting ot' the parts herein described,constructed, and arrangedsubstantially as specified.

NICHOLAS SEIBERT.
